Review: 5 out of 5 stars — Buying a second one because it’s that good - We installed this double-sided keypad door knob on our front door before May 2024 and after months of daily use, it has exceeded every expectation. It’s honestly one of the best home security purchases we’ve made — so much so that we’re buying another one right now for our back door. Safety was our top priority. We have an autistic child who can sometimes try to leave the house unexpectedly, and this lock has given us real peace of mind. Because it has keypads on both sides, there’s no simple knob to turn and walk out — a code is required — which adds an extra layer of safety while still allowing quick and easy access for adults. It helps prevent wandering while also keeping our home secure from intruders. The build quality is excellent. It feels solid, durable, and well-made — not cheap or flimsy. Installation was straightforward, programming codes was easy, and the keypad is very responsive. We’ve never had issues with it missing inputs or malfunctioning. Ours is installed on the front door and has handled everyday use and weather changes without any problems. The waterproof and weatherproof design really holds up and still looks and works like new. The key-alike dual cylinders are also a great feature, keeping things simple while providing backup key access if ever needed. This lock delivers security, reliability, and peace of mind all in one. The fact that we’re purchasing a second one for our back door says everything. If you’re looking for a dependable, well-built keypad lock for real-life safety and security, this one is absolutely worth it. Highly recommended.
Review: Perfect for autism home safety! - These installed quickly and worked immediately. They have made such a difference in the safety and function of our household. Two of my boys are autistic, and one has tried eloping multiple times. This worked exactly as we hoped and means that we can all breath easier knowing that the boys are safe. This is also a much better alternative to child safety locks we have tried that bolt into the door, because my daughter couldn't reach them to let herself out, and they couldn't be opened from the outside. This is a much safer alternative and is so convenient. I love how the door locks immediately upon closing, so we never have to worry about forgetting to lock it. Plus, we can't get locked out since we all know the combination. They also use normal batteries, so they don't require anything fancy to keep them running, and there are backup keys as well. They were worth every penny, and were affordable enough to get one for every exterior door.

### ⭐⭐⭐⭐⭐ Keyless entry!
*by I***E on March 12, 2025*

Great lock! I bought a second one just last week. After using for two years it does not work with the code anymore. Want to keep the code option so I bought another. I am in the U.S. but my lock is for my home in another country where the sun is hot and the rain is plenty and salt air...makes for rust...but I love this option for the people who take care of my home the cleaned and gardener and delivery person.
